A new joint system named ‘elastic-hinge joint system’ is proposed. This system shows a non-linear elastic restoring force-rotation relation and can realize origin-oriented frames. These properties can control damage and reduce permanent distortion in structures or in structural elements after a severe earthquake. This paper describes experimental results on a beam-column connection to which this joint system is applied. The purpose of this paper is to clarify the separation and rotation behavior of the elastic hinge joint. Based on the results, a theoretical model of this joint system is proposed.
